Students in our Confined Space Rescue Team Leader class (May 3-7, Sahuarita, Arizona) learn that a descender (like the Petzl I'D or CMC Clutch) is essential for mainline raising and lowering operations. The ability to grab and release rope under control (when lowering) and then act as a pulley (when raising) provides teams with an effective tool to conduct technical rope operations. For decades, the Petzl I'D has been one of the most common descenders and we have used it extensively in class. But there are several others out there as well. In addition to the MPD, CMC Rescue recently...
Descender FAQ Q: What types of descenders are available and how do you know which one to choose?A: Like rope grabs there are a zillion descender and friction control devices on the market.
